Hi all,

hope you are all doing well.

I am still trying to display pull quote between two columns.

lmt_parshape is really helpfull.

I need to add a 1pt gap to make the left column behave correctly,
but the right column remains shifted one line below the intended one.

Question1: any clue ?

Question2: is there a way to use the columnset system to produce a 
similar output ?

Thanks again for your feedbacks,
Garulfo
